    • A method including determining a public identifier for identifying a configuration of an apparatus, determining a common configuration certificate comprising a common configuration certificate identifier for verifying programming data, and determining a hardware certificate comprising the public identifier and the common configuration certificate identifier for associating a permitted combination of the apparatus configuration and the programming data. Furthermore, the method includes generating a dedicated package of the hardware certificates corresponding to the apparatus configurations allowed to be provided, encrypting the dedicated package of the hardware certificates using a public key, and storing the encrypted dedicated package of the hardware certificates with an identifier to a passive memory of the apparatus.
    • 一种方法,包括:确定用于识别装置的配置的公共标识符;确定包括用于验证编程数据的公共配置证书标识符的公共标识符;以及确定包括公共标识符和公共配置证书标识符的硬件证书, 装置配置和编程数据的组合。 此外,该方法包括生成与允许提供的设备配置相对应的硬件证书的专用包,使用公钥对硬件证书的专用包进行加密,并且将加密的硬件证书的专用包存储为标识符 该设备的被动记忆。

    • The exemplary embodiments or the invention provide at least a method, apparatus, and program of computer instructions to perform operations including receiving a challenge from a prover device, reading and saving an old value of a selected platform configuration register, obtaining at least one measurement or property and forming a new platform configuration register value, where the forming includes calculating a cryptographic hash over the old value of the platform configuration register and the obtained at least one measurement or property, triggering, with the trusted software, an attestation by sending a challenge to a trusted platform module/mobile platform module, and sending by the prover device a device certificate, attestation, at least one measurement or property, and old platform configuration register value to the verifier. Further, the exemplary embodiments or the invention teach sending a challenge to a trusted software of a prover device, and receiving by the verifier device a device certificate, attestation, at least one measurement or property, and an old platform configuration register value from the prover device, checking by the verifier device that extending the old platform configuration register value with the at least one measurement or property results in a new platform configuration register value that has been attested, and using the new platform configuration register value in attestation of the prover device.
